you must be on the main deck in foul weather, wear yourlife jacket. You must always wear an inherently buoyantlife jacket whenever you are handling lines or areotherwise involved in underway replenishment ortransfer operations.A ships deck has many tripping hazards, such ascleats, bitts, and pad eyes, as well as larger obstacles,such as boat davits and winches. Learn their locations sothat if you must go on deck at night, you will have abetter chance of avoiding these hazards.Dont sit or lean on lifelines. When the sea isunusually rough, a safety line may be rigged on the maindeck. When you are moving along the deck, you shouldstay inboard of, and hold on to, the safety line.The flight decks of aircraft carriers are particularlyhazardous areas. Beware of propellers and jet blast!Often, propellers are invisible because of the speed atwhich they rotate. They can act just like a meat slicer; soyou need to use extreme care when walking or workingnear propeller-driven aircraft.Jet planes present other hazardsa person can besucked into the jets intake, be burned, or be blownoverboard (or against an object) by its exhaust. Keep offthe flight deck if you dont work there. Because ofminimum lighting requirements, nighttime is especiallyhazardous on the flight deck. When working on theflight deck, always wear your ear protectors when jetengines are running. One other cautionSmoking isprohibited on the flight and hangar decks and in all fueland ammunition-handling spaces.In general, the same rules apply to ships withoperating helicopters. Only authorized personnel arepermitted in the landing area during helicopteroperations. Those personnel must wear properprotective clothing and equipment. During verticalreplenishment operations, keep out from under loadsand stay clear of the unloading area until the helicopterhas departed. Keep the landing area free from loosedebris or foreign object damage (FOD) that may beblown about by the downwash from the rotor blades orsucked up by jet intakes.During flight quarters, the flight deck of an aircraftcarrier is a dangerous place. This deck, combined withthe hangar deck, magazines, and shops, provides theequivalent operating facilities of a large airfield.However, the hazards associated with aircraftoperations are focused into a relatively small area.Therefore, personnel are exposed to a greater potentialof danger.REVIEW 3 QUESTIONSQ1.

They are safety barriers toprevent personnel from falling or being washed over theside. Never sit, lean, or stand on any lifelineif the shiptakes a sudden roll while you are leaning against alifeline, you could fall overboard.Never remove lifelines without permission from theproper authority. When removing a lifeline,19-6Student Notes:
